All manuals I found describe how hydro module of ABS works, when braking - how input and output valves are opening and closing depending on the braking processes - but no one describe their state during driving. I guess the input valve is of NO type and de-energized while driving. Is the...
Yes, one like for "starting relays for a refrigerator. When the motor current drops enough the contacts open the starting winding". They may not be sometimes available of a necessary size. Their paralleled coils would bear running winding current, but their contacts in series switch on and then...
Who think it is possible to effectively parallel current relays ? For instance, if a 1/2 HP one is not available, one can use in necessity two 1/4 HP relays (however, it is better to add by that an ordinary NO relay to bypass the current to the starting winding). Somebody done this ?
Is there a diagnostic car fault reader/ clearer dedicated especially to car climate control ? Or some that is most suitable for that purpose ? (In case one does not need no other functions)
I meant there seems to be no one being shown or sold in internet. Must be very expensive (however, if a usual relative pressure manometer is not - why an absolute pressure one should be ?)
Why there are gas pressure differential manometers with 1 Pa resolution, but the barometric absolute pressure ones with only 10 Pa (0.1 mBa)resolution ?
I understand it so. To set constant head control you imitate full demand (open 100 % valves), set the pump speed and balance the flows (adjusting the speed) untill all demands are satisfied. You note the head (for instance 10 m) and make it the SP. The pump then will be keeping this head.
To...
In a closed water circulation system with 2-way valves at the consumers and the constant head control, when the valves close, the system resistance and head increases, the system curve comes up and the control through an invertor lowers pump's rpm. Pump curve goes down and the head is kept at a...
Thank you but if I understand correct one is OD another is "nominal size". The ommitted inconsistency in designation will stay yet for long time as it seems they simply "dont care" about what they sell.
In short, I think, they planned the system with steel pipes but finally put instead PPR with the same OD. Hence big losses. There were other mistakes - idiotic - like two pumps working ... towards each other ! (this I had corrected already), in the heat exchanger (water/glycol) 2 flows moving in...
